Error in directive draggable bind hook: "ReferenceError: 'TouchEvent' is undefined"

I've been using your draggable directive on a reporting page and really appreciate how easy it is to use. Unfortunately, most of our users are still using IE 11 (I know, I know...). Just noticed that your directive raises this error in IE 11 on page load:

Error in directive draggable bind hook: "ReferenceError: 'TouchEvent' is undefined"

The good news is that it doesn't seem to be a breaking error. The elements that use your directive are still draggable with no issues. But you might want to see if there's a way to gracefully prevent that error. Thanks!

I think this problem will be resolved through my PR, which still isn't merged:

Many thanks!
